The epitheca covers the costules. In the Philippines, in the 

 tropical zone, the frontal ornament is much accentuated, especially 

 the tuberosity placed at the end of each costule which is very salient. 

 Unfortunately we have not had time to make any sections in spite of 

 the abundance of materials. 



Biology. — This species is extremely prolific. Almost all our spec- 

 imens were ovicelled and ancestrulated. The laying of eggs and the 

 fixation operate almost all the year without any interruption. The 

 larva fixes itself on all marine objects; pebbles (rare), shells, corals, 

 bryozoa, sponges, nullipores, foraminifera, but never on algae. It 

 prefers shallow waters from 30 to 50 meters, but it lives very well 

 at the depth of 372 meters. It does not pass beyond the polar 

 circle. With the same fecundity, it has lived in the ancient seas 

 since the Eocene (Lutetian) both in Europe and America.
